CICSplex TCPIP Statistics attribute group

The data returned by the CICSplex TCPIP Statistics attribute group monitors the activity of your TCP/IP services. It includes the current and peak numbers for individual sockets and indicates when the limit set by MAXSOCKETS has been reached. Most of this data is accessed online using the EXEC CICS COLLECT STATISTICS TCPIP CICS Transaction Server command.

Average MAXSOCKETS delay time Is the average length of time (in seconds accurate to thousandths of a second) that current requests have been waiting because the CICS regions has reached the MAXSOCKETS limit. The valid format is a floating-point number, accurate to three decimal places.

CICS Region Name Indicates the job name or modify ID of the CICS region being monitored. Each CICS region in a z/OS operating system has a unique name. This name is an alphanumeric string, with a maximum of eight characters, and case sensitive. CICS region names are always in uppercase characters.

Current Active IP SOCKETS Is the current number of active IP sockets managed by the CICS sockets domain. The value format is an integer of maximum four bytes.

Current Active SSL SOCKETS Is the current number of SSL sockets. The value format is an integer of maximum four bytes.

Current Delayed at MAXSOCKETS Is the current number of create socket requests delayed because the system is at the MAXSOCKETS limit. The value format is an integer of maximum four bytes.

Current Delay Time at MAXSOCKETS Is the delay time (accurate to three decimal places) for the current create socket request that was delayed because the system is at the MAXSOCKETS limit. The value can be entered in the hh:mm:ss.ddd format, for example, 00:20:00.567 or as sssssss.ddd, for example, 1200.567. If you are using variable substitution, the value in this example would display as 1200567.

Current Inbound Sockets Is the current number of inbound sockets. The value format is an integer of maximum four bytes.

Current MAXSOCKETS delay time Is the current length of time (accurate to three decimal places) that create socket requests are waiting because the CICS regions has reached the MAXSOCKETS limit. The value can be entered in the hh:mm:ss.ddd format, for example, 00:20:00.567 or as sssssss.ddd, for example, 1200.567. If you are using variable substitution, the value in this example would display as 1200567.

Current Outbound Sockets Is the current number of outbound sockets. The value format is an integer of maximum four bytes.

Current Persistent Sockets Outbound Is the current number of persistent outbound sockets. The value format is an integer of maximum four bytes.

Maximum Sockets Limit Is the maximum number of TCP/IP sockets. The maximum number of IP sockets is managed by the CICS sockets domain. The value format is an integer of maximum four bytes.

Maximum SSL TCBs Is the maximum number of TCP/IP SSL sockets. The maximum number of SSL sockets is managed by the CICS sockets domain. The value format is an integer of maximum four bytes.

Number Inbound Sockets Created Is the total number of inbound sockets created. The value format is an integer of maximum four bytes.

Number Outbound Sockets Created Is the total number of outbound sockets created. The value format is an integer of maximum four bytes.

Number Outbound Sockets Closed Is the total number of outbound sockets closed. The value format is an integer of maximum four bytes.

Number Times at MAXSOCKETS Is the number of times the maximum number of IP sockets limit (MAXSOCKETS) was reached. The value format is an integer of maximum four bytes.

Open Status Indicates the status of the TCP/IP service. These are the values: Open, Closed, Closing, ImmClosing.

Origin Node Is the combination of z/OS System ID (SMFID) and CICS region name. The value format is an alphanumeric string, maximum 32 bytes, and case sensitive.

When a situation is true, the system compares the origin node name in the attribute to the names of managed systems assigned to the item. If the origin node name matches the name of a managed system, the status of the item changes accordingly. If the names of the origin node and the managed systems do not match, the status of the item remains unchanged.

Peak Delayed at MAXSOCKETS Is the peak number of create socket requests delayed because the system has reached the MAXSOCKETS limit. The value format is an integer of maximum four bytes.

Peak Inbound Sockets Is the peak number of inbound sockets. The value format is an integer of maximum four bytes.

Peak Outbound Sockets Is the peak number of outbound sockets. The value format is an integer of maximum four bytes.

Peak Persistent Sockets Outbound Is the peak number of persistent outbound sockets. The value format is an integer of maximum four bytes.

System ID Indicates the four character name that uniquely identifies an active z/OS operating system within a given CICSplex. The value format is an alphanumeric string, maximum four characters, and case sensitive. z/OS System IDs are always in uppercase characters.

Timeouts while at MAXSOCKETS Is the total number of create socket requests that were timed out while delayed because the system had reached the MAXSOCKETS limit. The value format is an integer of maximum four bytes.

Total Delayed at MAXSOCKETS Is the total number of create socket requests that were delayed because the system had reached the MAXSOCKETS limit. The value format is an integer of maximum four bytes.

Total Delay Time at MAXSOCKETS Is the total delay time (accurate to three decimal places) for the create socket requests that were delayed because the system is at the MAXSOCKETS limit. The value can be entered in the hh:mm:ss.ddd format, for example, 00:20:00.567 or as sssssss.ddd, for example, 1200.567. If you are using variable substitution, the value in this example would display as 1200567.

Total Sockets Created Is the total number of inbound and outbound sockets created. The value format is an integer of maximum four bytes.

SSLcache setting Specifies whether SSL is to use the local or sysplex caching of session IDs. Sysplex caching is only allowed if multiple CICS socket-owning regions accept SSL connections at the same IP address. These are the values: CICS or SYSPLEX. The default value is CICS.
